About Carbon Steel, Alloy Steel, Spring Steel, and Cast Iron

Low-Carbon Steel U-Channels

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength.

Low-Carbon Steel 90° Angles

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength.

Zinc-Galvanized Low-Carbon Steel 90° Angles

These 90° angles are zinc galvanized for good corrosion resistance.

Low-Carbon Steel T-Bars

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength.

Low-Carbon Steel I-Beams

Made of rigid low-carbon steel, these I-beams are often used in construction, framing, lifting, and hoisting applications.

Low-Carbon Steel H-Bars

Made of stiff low-carbon steel to deflect less under load, these H-bars are commonly used in machine bases, construction, platforms, and frames.

Low-Carbon Steel Hex Bars

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength.

Ultra-Machinable 12L14 Carbon Steel Hex Bars

The lead additive acts as a lubricant, which allows 12L14 carbon steel to withstand very fast machining. It's used to fabricate a wide variety of machine parts.

Easy-to-Machine 1215 Carbon Steel Hex Bars

A lead-free alternative to 12L14, 1215 carbon steel contains the same amount of sulfur and phosphorus for excellent machinability. It is often used for shaft couplings, studs, and pins.

Multipurpose 4140 Alloy Steel Hex Bars

Hardened Multipurpose 4140 Alloy Steel Hex Bars

These hex bars are hardened for increased abrasion and impact resistance. They are also stress relieved to reduce the chance of warping during machining.

Multipurpose 4140 Alloy Steel Hex Bars

Also known as chrome-moly steel, this versatile 4140 alloy steel is used for a wide range of parts, such as gears, axles, shafts, collets, and die holders. It resists fracturing from repeated stress.

Steel Hat Channel

In addition to creating space inside walls or ceilings—to prevent dampness or make room for insulation—these channels can also be used to level or resurface them.
